摘　　要：以纳米MCM-41孔道为模版,组装制备了二溴对氯偶氮胂(DBC-ASA)纳米簇合物。采用化学分析、粉末X-射线衍射、77 K N2吸附-解吸附、红外光谱、固体扩散漫反射光谱及发光光谱表征了制备的(MCM-41)-(DBC-ASA)主-客体纳米复合材料。结果表明,DBC-ASA成功地组装在了主体MCM-41中,并且处于主体分子筛材料的纳米孔道中。(MCM-41)-(DBC-ASA)纳米复合材料具有作为发光材料的应用前景。The channels of nanometer MCM-41 was used as template and the nanoclusters of dibromo-p-chloroarsenazo（DBC-ASA） were prepared by incorporation.Chemical analysis,powder X-ray diffraction,nitrogen adsorption-desorption at 77 K,infrared spectroscopy,solid state diffuse reflectance spectroscopy and luminescence spectra were employed to characterize the prepared（MCM-41）-（DBC-ASA） host-guest nanocomposite materials.The results showed that DBS-ASA has been successfully encapsulated in the host MCM-41 and located in the nonoscale channels of the host molecular sieve material.The guest DBC-ASA partly occupied the nanoscale channels of the molecular sieve.The（MCM-41）-（DBC-ASA） nanoscale composite material has the application prospect as luminous material.
